This would be the green light would normally be just above where the X and Y buttons would be? If so, then no, that light does not come on.

Yeah, I'm talking about the LED above the X/Y buttons.
If you watch this video, you'll see how the bootup should look.

If that LED isn't coming on, then there's something wrong between the GPA and the Raspberry Pi, because the green light is a signal from the Raspberry Pi. It basically means that the Raspberry Pi has taken control of the power (On/Off).

If the Raspberry Pi is installed/soldered upside down, it may exhibit this behavior. Otherwise, I'd guess maybe a faulty solder joint (or broken pin) between the Pi and GPA.

This is where photos would really help.

Understood. I have attached a photo and it shows how I've also covered the Pi GPIO pins so that they don't contact anything else.

While the electrical tape is a great way to protect them from contacting, it makes them hard for me to see. Smile

But, the upside (no pun intended) is that I can see that the Pi is right-side-up.

LOL, I like your style.

Do you need to see the header pins? I soldered all of them and they are definitely stuck on there.

If you plug power into the GPA's microUSB socket, does it behave any differently?

What about (without batteries) if you plug power into the Pi's microUSB port?

Do either of those help it boot up?

Do you have an adapter to let you plug HDMI from the Pi to a TV or monitor?

Smile I would only look at them to be 100% sure that they look soldered well. I have seen some that were questionable.

The other thing to check is if the SD card is working well. Maybe it's not fully seated? Maybe the SD card itself is bad? Maybe the image didn't get written properly?

ApplePi Baker is also what I use, so I don't see why that would be a problem. The behavior you are talking about would likely occur if the image was bad, though. It seems to not be booting up.

Hmm, plugging directly into the MicroUSB port on the Pi also powers the screen, just white though.

I'll have to try to find my mini-HDMI adapter tomorrow morning in order to try that last one.

I really appreciate your assistance! I've never been assisted so well.

I'll update this post tomorrow if that is okay with you?

I appreciate that you understand that we are all here learning together about how to make something cool for everyone to enjoy.

I'm always worried that people will be upset if things don't go perfectly immediately. Really, I have been pleased with your (and all the other builders') willingness to work through any issues like this. I want everyone to be pleased with their kit and end result.

If you have the mini HDMI adapter, that will make debugging a lot easier. Then we can boot it up without the GPA connected to narrow down to the possibilities.

At this point, I really think it has something to do with the SD card or the image file.

Tomorrow would be great, because I should probably get to some other things like sleeping soon.

Its really not a problem at all, I'm glad that you look at all of this as being a learning experience for everyone. Another think that I really like is that you also learn from these interactions and make improvements to the design. Its really a win-win.

I've gone ahead and resoldered the GPIO pins and I'm now working on creating a new image, I'm going to try with a different SD card -- strangely enough, looking at the SD card, I'm not seeing any folders for emulators, etc. Is that normal or is there something wrong with the SD card do you think?

I'm attaching an image of my pin headers for your review. Thank you so much for continuing to assist me.

You mentioned ApplePi-Baker, so I assume a Mac.

When you burn the image to your SD, I think it will (software) eject it when done. If you pop it back in your Mac, it will mount the device (kinda).

The SD card will have 2 partitions: boot and root.

The boot partition is pretty small (like maybe 60megs, IIRC). This is a FAT partition, and the Mac can mount it. That's what you'll see if you plug it in to your Mac. The main thing people might do with that is to edit the config.txt file (which sets some boot options for the Raspberry Pi). See https://www.raspberrypi.org/documentatio...fig-txt.md

The root partition won't be viewable (without special tools) on the Mac. If you're expecting to see emulators etc., they'd be in the root partition, but you wouldn't see that.

If you can see the boot partition on your Mac, that's a pretty good sign that the image worked. I have heard of SD cards that don't work on the Pi, but I think that's unlikely.

What size SD are you using? If you have a different SD, that'd be a good thing to try. Again, if you can try it with a HDMI adapter, it's definitely worth it. Then you can unplug the Pi from the GPA and boot up using microUSB power and HDMI (which eliminates any GPA issues for the moment).

I have great news to report! I now have everything working perfectly! The problem was my SD card, it was an off-brand, I went to the store and purchased a SanDisk 64GB SDHC and it works perfectly! Thank you, thank you, thank you for taking so much of your own time to assist me! This is awesome, and so are you! Please keep up the great work!
